The difference between stainless steel and stainless steelStainless steel refers to acid, alkali, salt and other chemical erosion corrosion of steel. Advent of stainless steel since the beginning of this century, but now has more than 90 years of history. Stainless steel is a serious achievement history of Metallurgy in the world of creation, stainless steel modern industrial and technological progress has laid an important material and technological foundation. Many stainless steel, properties, which constitute the categories in the process. By organization structure points, is divided into horse's stainless steel (including precipitation hardening stainless steel), and iron pigment body stainless steel, and Austrian's body stainless steel and Austrian's body added iron pigment body double phase stainless steel, four class; by steel in the of main chemical components or steel in the of some features Yuan has never classification, is divided into chrome stainless steel, and chrome nickel stainless steel, and chrome nickel Mo stainless steel and low carbon stainless steel, and high Mo stainless steel, and high pure stainless steel,; by steel of performance characteristics and use classification, is divided into resistance nitric acid stainless steel, and resistance sulfuric acid stainless steel, and resistance points corrosion stainless steel, and resistance stress corrosion stainless steel, and High-strength stainless steel; classified by functions characteristic of steel, divided into low temperature stainless steel, non-magnetic stainless steels, superplasticity of free cutting stainless steel, stainless steel and so on. Current classifications are organized by the steel structural characteristics and the chemical composition of steel properties and the phase separation of the two way classification. General there are Martensitic stainless steels, ferritic stainless steel, austenitic stainless steels, duplex and precipitation hardening stainless steel, stainless steel, or category is divided into two large chromium nickel stainless steel and stainless steel.
stainless steel General for anti-corrosion sex of environment, and medical devices and life supplies
so-called "not rust iron", is will recycling of scrap, and lead, and steel, by two times melted down processing, after off "HIV/AIDS" disposal and into, traditional of detection approach is with magnet, and this products with traditional approach is cannot distinguish of, natural is sneak, blindfolded has many of engineering selection, thus openly to into has a and a decorative site, boarded has a site and a site luxury curtain wall. This title was born since the exposure of the focus, and occupy approximately 65% of the market, while the real GB SUS304 stainless steel products because of high price and no market.
in the current market "stainless steel" products to have its share of 65% is its price plays an important role, GB about around 20,000 yuan per ton price stainless steel products, price per ton is about 1 GB 7075 aluminum alloy. Around 60,000 yuan, while "stainless steel" price of only 5000-7000 Yuan per ton and then look at each of those three the tensile strength of the material: stainless steel 530-620MPa GB, GB 7075 aluminum alloy 540-560MPa, "stainless steel" 160-180MPa. Apparently "stainless steel" tensile strength could not reach 1/3 strength of stainless steel, are extremely vulnerable to attack.
